/**

|
* SECTION:gtkapplication
|
|
* @title: GtkApplication
|
|
* @short_description: Application class
|
|
*
|
|
* #GtkApplication is a class that handles many important aspects
|
|
* of a GTK+ application in a convenient fashion, without enforcing
|
|
* a one-size-fits-all application model.
|
|
*
|
|
* Currently, GtkApplication handles GTK+ initialization, application
|
|
* uniqueness, session management, provides some basic scriptability and
|
|
* desktop shell integration by exporting actions and menus and manages a
|
|
* list of toplevel windows whose life-cycle is automatically tied to the
|
|
* life-cycle of your application.
|
|
*
|
|
* While GtkApplication works fine with plain #GtkWindows, it is recommended
|
|
* to use it together with #GtkApplicationWindow.
|
|
*
|
|
* When GDK threads are enabled, GtkApplication will acquire the GDK
|
|
* lock when invoking actions that arrive from other processes. The GDK
|
|
* lock is not touched for local action invocations. In order to have
|
|
* actions invoked in a predictable context it is therefore recommended
|
|
* that the GDK lock be held while invoking actions locally with
|
|
* g_action_group_activate_action(). The same applies to actions
|
|
* associated with #GtkApplicationWindow and to the 'activate' and
|
|
* 'open' #GApplication methods.
|
|
*
|
|
* To set an application menu for a GtkApplication, use
|
|
* gtk_application_set_app_menu(). The #GMenuModel that this function
|
|
* expects is usually constructed using #GtkBuilder, as seen in the
|
|
* following example. To specify a menubar that will be shown by
|
|
* #GtkApplicationWindows, use gtk_application_set_menubar(). Use the base
|
|
* #GActionMap interface to add actions, to respond to the user
|
|
* selecting these menu items.
|
|
*
|
|
* GTK+ displays these menus as expected, depending on the platform
|
|
* the application is running on.

|
|
* </example>
|
|
*
|
|
* GtkApplication optionally registers with a session manager
|
|
* of the users session (if you set the #GtkApplication:register-session
|
|
* property) and offers various functionality related to the session
|
|
* life-cycle.
|
|
*
|
|
* An application can block various ways to end the session with
|
|
* the gtk_application_inhibit() function. Typical use cases for
|
|
* this kind of inhibiting are long-running, uninterruptible operations,
|
|
* such as burning a CD or performing a disk backup. The session
|
|
* manager may not honor the inhibitor, but it can be expected to
|
|
* inform the user about the negative consequences of ending the
|
|
* session while inhibitors are present.

* All GTK+ functionality that is available via commandline arguments
